Abstract
A method performs iterative decoding of information coded by an error correction code. The method includes: defining a transcendent first function representing a quantity to be evaluated for the decoding method; defining a quantized second function approximating the first function; computing first values of the second function obtained based on first arguments; the first values being not null and the first arguments being variable in a limited range having a maximum limit; computing second values of the second function obtained on the basis of second arguments, the second values being null; and generating a look-up table representing the first function and containing the first and second values associated to indexes correlated to said first arguments and to an expected maximum limit.
